dev-qt/qt-creator fails to build with sys-devel/clang:10. New version of clang is built without split libraries, and qt-creator fails to link to resulting clang libraries. Reproducible: Always Steps to Reproduce: 1. Copy and modify qt-creator ebuild to drop llvm/clang-8 compatibility restriction.

This is related to bug #710306. In the >=clang-10 ebuilds, the "-DBUILD_SHARED_LIBS" flag has been set to "OFF". This causes problems when building various packages, including qt-creator and mesa. This is a list of broken packages for Fedora, where they're considering making the same change: https://fedoraproject.org/wiki/Changes/Stop-Shipping-Individual-Component-Libraries-In-clang-lib-Package#Dependencies This change was apparently made to fix mlir, but it is breaking other packages. I'm not sure if any of these packages have upstream fixes or patches.
Same thing happens with dev-qt/qt-creator-4.8.2 (it doesn't have LLVM_MAX_SLOT). I have both llvm:9 and llvm:10 installed.

Should the fixed version be stabilized now, because LLVM 10 became stable?

Well, it looks like it's a pretty long task, because it's require Qt 5.15. Maybe the default USE flags should be changed? To make things just work by default?

as the latest qt-creator requires Qt 5.15, is it possible to backport the patch to qt-creator-4.10.1?
I have backported the patches for LLVM 9 and 10 to qt-creator-4.10.1, simply by taking the relevant commits from upstream git repository. Morever the ebuild needs a few simple changes

I don't know which is the purpose of the qt-creator-4.12.0-libclangformat-ide.patch but version 4.10.1 compiles successfully, is needed for runtime?
